Next comes the sanding.
There's some file-work to clean up the ends, but the general shape is set.
Now comes sanding, starting with 220 grit and ending with 6000 grit.
A word about sandpaper grits. 220 is still a shaping grit. It'll cut and remove
material. I'll use a brass strip, a rubber backed strip, and thick, stiff
leather as a backing, and finish out the shape.
320 cleans up the 220 marks , and still moves a bit of material, using the
leather backing.
400 and 600 clean up previous scratches, and at 800 I'll move out onto the
popcorn to begin highlighting.
1000, 1200, go quickly, and things begin to shine, 2000 and 2500 more so.
Then to the polishing papers, blue (roughly 2000 g) pink (4000) and green (6000)
These are the fun items. I wish you could see how the surface changes.
Sometimes folks are overly impressed with the work involved in going up to the
higher grits in finishing.
Really, the work is done below 600 grit. After that, things go very quickly, and
only a few minutes are taken at each higher grit.
I think it's hard to argue, though, that the extra time is wasted.
I'll finish cleaning up the bow, and do the nit-picking this week-end.
